{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map displays world countries as filled paths using a Mercator projection. The visualization loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON with the `feature` function from topojson. Each country path is rendered through D3’s `geoPath` and `geoMercator` APIs, with CSS styling applying a green fill and light stroke. The map is drawn as static SVG elements within a 960x500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/696e6754bfa343f986fe96e4b0495654?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
